# Extended Window Manager Hints ## Identification [[Xen paravirtualization|Xen PV]] exposes paravirtual interfaces to guests. [[herbstluftwm|herbstluftwm]] is a scriptable tiling window manager controlled by `herbstclient`; [[Extended Window Manager Hints|EWMH]], XRandR, and Xinerama concern desktop interoperability and multiple displays. ## Notebook evidence - [[Scanned_20260730-1719#PDF page 69 — Xen constants and Herbstluftwm control|PDF page 69: Xen constants and Herbstluftwm control]] — The page shifts from hypervisor memory/constants to the guest’s display-control plane. It asks how a lightweight VM can still expose a scriptable, remotely manageable multi-monitor desktop. ## Relationships and overlays The source places this note in a shared evidence cluster with [[herbstluftwm|herbstluftwm]] · [[Scanned_20260730-1706|Scanned_20260730-1706]] · [[Xen paravirtualization|Xen paravirtualization]]. Within the larger collection, this evidence extends [[Vendor-Agnostic Recovery|vendor-agnostic recovery]] and [[Continuity Architecture|continuity architecture]] by showing how software, hardware, identity, and pre-OS control depend on recoverable interfaces. ## Evidentiary status and open leads Identify host, guest, display transport, GPU mode, and whether Xinerama/XRandR reports were local or virtual. ## Source - [[Scanned_20260730-1719|Scanned_20260730-1719]]
